To all whom it may concern..-

Be it known that I, CHARLES H. MUCKEN- HIRN, a citizen of the United States, residing at Salem, county of Salem, State of New Jersey, have invented a certain new and useful Improvement in Trap-Joints; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to couplings employed to connect the bowls of water-closets to the soil-pipe and at the same time to firmly secure both the soil-pipe and the bowl to the floor of the building.

In the drawings, Figure 1 is a section of that part of the coupling which is attached to the bowl. Fig. 2 is a section of that part of the coupling which is connected to the floor. Fig. 3 is a section of a coupling in which the depending ring is conical in shape. Fig. 1 is a section of the floor connection used with the ring of Fig. 3.

A indicates the bottom of the bowl, to the bottom surface of which is secured a ring 1. The ring is provided with a horizontal flange 2 around its upper edge and with a couplingflange 3, which is made in two sections, and each of which sections extends about onequarter of the way around the lower edge of the ring. These flanges 3 and 4 extend substantially parallel with the flange 1.

That part of the coupling by which the pipe is secured to the floor consists of the ring 5, provided with bolt-holes through which screws are inserted to secure the ring to the floor. This ring is provided with a rabbet 6, into which is expanded the upper end of the lead soil-pipe 7, and the soil-pipe is preferably secured to the ring by soldering. The rabbet 6 is of a depth such that after the expanded rim of the soil-pipe has been expanded into it there still remains a rabbet inwhich engages a flange 6 on the upper end of a locking-ring 8, which locking-ring is inserted within the soil-pipe, and the two rings 5 and 8 are secured together with solder or in any other appr opriate way.

The ring 8 is provided on its lower edge with flanges 10 and 11, that extend inward. Each of the flanges 10 and 11 is a partial flange extending only a part way round the ring 8, and the ring 1 and the ring 8 are locked together after the ring 1 has been secured to the bowl and the ring 8 has been secured to the floor by inserting the ring 1 into the ring 8 with the flanges disposed so that the flanges 3 and 4 will pass through the openings between the ends of the flanges 10 and 11, and the bowl is then given a quarter-turn.

Previous to interlocking the parts together a gasket 12 of any suitable material is laid over the surface of the ring 5 and engages closely between the ring 5 and the flange 2, that projects from the ring 1, under such compression as may be produced-thereon by forc- .ing the ring 1 downward and turning it forcibly until the flanges engage and interlock th parts.

In the form shown in Figs. 3 and 4 the ring 1 is conical throughout a part of its surface, and the coupling, which is secured to the floor, has a depending ring part 22, whose inner surface at the lower end is cut to leave an opening 62. The upper end of the lead soil-pipe is expanded and soldered. The ring 81 is placed over this, and the rings 22 and 81 are secured together by soldering. The ring 81 in this case is provided with the partial flanges 101, which engage and hold complementary flanges that extend from the hanging ring 1. The structure is substantially like the one shown in Figs. 1 and 2, except thatthe hanging rings are made as sections of partial cones instead of being made as sections of cylinders.

What I claim is 1. In a coupling to secure the bowls of water-closets to soil-pipes, the combination of a soil-pipe, a ring secured to the bowl and provided with partial flanges, a ring adapted to be secured to the inside of the upper end of the soil-pipe, and provided with partial flanges arranged to interlock with the flanges on said first-mentioned ring, and a third ring secured to the outside of the upper end of the soil-pipe, substantially as described.

2. In a coupling to secure water-closets to soil-pipes, in combination with a soil-pipe, a plurality of interlocking rings secured respectively to the bowl and to the inside of the u p per end of the soil-pipe, and an additional ring adapted to be secured to the outside of the soil-pipe and focus of said interlocking rings by soldering, substantially as described.

3. Acoupling to secure water-closets to soilpipes, comprising, in combination with a soil pipe, a pair of concentric rings one of which is secured to the floor with the end of said soilpipe engaging between them, there being a In testimony whereof I sign this specificapartial flange extending inwardly on one of tion in the presence of two Witnesses. sai rings, and a ring secured to the bowl and w x \T provided With similar though outwardly-ex- (JHARLES MULKENHIR 5 tending flanges adapted to interlock with the Witnesses:
